4.
Power off the 5420 and connect the flat panel display to the
5420 using a 50–position IDC connector.
Improperly attaching a flat panel to the 5420
SVGA card could damage the Chips & Technolo-
gies video chip. The problem is due to flat panels
having connector pins that are not clearly marked
and assumptions are made as to the location of
pin 1. For example, Sharp LM32008F and other
Sharp Quarter VGA panels have this problem.
The silk-screen for CN1 on these panels is placed
next pin 12. This causes the user to assume that
pin 12 is pin 1 and as a result, the panel is wired
backwards. This in turn causes damage to the
video chip.
Carefully read the flat panel documentation and
diagrams, which clearly identify the placement of
pin 1, so that damage to the 5420 can be avoided.
Octagon assumes no responsibility for any
damage caused to flat panel displays and/or Micro
PC video cards if the display is connected
incorrectly.

This is PIN 1
